steve2 - The GB know very well the organization is in extremely hot water over its shocking policies on and procedures for responding to child sexual abuse in the local congregations. How many rank and file Witnesses know that?
I would assume that not many know of it. I remember, when I was still active, hearing a comment made by one sister during a meeting. She criticised other religions for child sexual abuse—mainly the Roman Catholic church—and then said that Jehovah's Witnesses don't have that problem. She said that "we" don't have to worry about it because, allegedly, Jehovah takes care of his organisation. I still didn't know about the issue at the time, so I was willing to believe it. The problem is that none of us checked the news to see whether that's the case. She was really making an uninformed statement based on her research which... well... was based on what the Governing Body said. (Remember Stephen Lett calling child sexual abuse "apostate-driven lies"?)
I'm glad I checked the issue myself later on when I heard Anders Andersen talking about it on another website. I heard of it even before that, but I refused to believe it since the "apostates" that were saying it were really aggressive about it. That attitude just confirmed my "conviction." But then I read Anders Andersen's posts about child sexual abuse, and I saw that he was just stating the facts while not being aggressive or insulting. Then I searched the news and watched the Australian Royal Commission.
So... based on my experience, not many know of the child sexual abuse. Unfortunately.
